A "star" looking object traeling across the sky, dissapearing behind a tree, then coming back out brighter then fading to blackness.

My famiily and I were camping that weekend on Petit Jean Mountain (in Ark.),and I love the topic of UFOs, so I thought I'd watch the stars. Since I live in Little Rock, the city lights block out most of the stars. Anyway, Me and my brother were watching the stars when we see an object, more like a star, traveling across the sky. I know it wasn't a meteor, because I commonly watch for those. I also knew it wasn't a satelitte, because they havesome sort of blinking to them. It looked like a star going across the sky. I kept my eye on it until it went behind a tree. I didn't se it come out the other side, so I thought it was wierd. A few minutes later, I see this BRIGHT light (like 50 stars put together) come back the opposite direction from behind the same tree. I saw it and shined my flash light at it and it became dimmer and dimmer until it was the same "star" I had seen earlier traveling across the sky. I shined my light at it again, and it faded into nothingness. I guess it became as black as the night sky. It wasn't a helicopter, because there was no noise, or a plane for the same reason. It just traveled across the sky in a straiht line. a white light.

((NUFORC Note: We cannot be certain what it was the witness observed, but it seems reminiscent of an orbitting object. The fact that it dimmed is characteristic of a satellite as it "flies" into the shadow of the Earth, and is no longer illuminated by sunlight. There are several very large objects in orbit that have a very bright reflection albedo, e.g. Mir, the Space Shuttle, and the I.S.S.. Also, the Iridium satellites can cause some of what the witness describes. However, we are not certain. PD))
